There's no problem using language to talk about language. I think you're referencing performative contradictions rather than self-referential paradoxes. The cases where the propositions become inaccurate is where the terms used have no concrete definition. The point is, the proposition "This sentence is false" isn't even sensible, because "This sentence" isn't something that can be true or false. It's just two words put together in a tricky way.
